説明（英語）: Genus of about 15 species of cycads found mainly on dry, stony slopes and in semi-desert and dry, open woodland (and, rarely, at rainforest margins) from Madagascar to S. and S.E. Asia, Australia, and the Pacific islands. They have whorls of pinnate, stiff, leathery leaves, with linear-lance-shaped to sickle-shaped leaflets. Dioecious inflorescences arise from the centres of the leaf rosettes. The large male inflorescences are cone-like, up to 80cm (32in) tall, and usually covered in woolly hairs; the female inflorescences consist of loosely arranged, modified leaves, to 30cm (12in) long, bearing ovules on the margins. Cycas species are generally cultivated for their palm-like appearance. In frost-prone climates, grow in a temperate or warm greenhouse, or as foliage houseplants. In warmer climates, they make excellent specimen plants.

耐寒性（英語）: Frost tender; C. revoluta will survive short periods near to 0°C (32°F) if given some protection.

栽培（英語）:

繁殖（英語）: Sow seed at 15-29°C (59-84°F) in spring. Remove and pot up suckers in spring.

病害虫（英語）: Susceptible to red spider mites, mealybugs, and scale insects under glass. Cycas species may be damaged by chemical pesticides; use soft soap or biological controls.
